feat: add CuriousAlgorithm and CuriousPlayer

[trethore]

Summary

This PR adds Curious, a new skill point solver still focused on having the best performances possible.

What changed

In this PR you can find:

• Added CuriousAlgorithm and registered it in the algorithm registry.
• Added CuriousPlayer, a lightweight player implementation used by the new algorithm.

New algorithm

Curious Algorithm is the more aggressive version of Starving Goblin. It keeps the same fast paths for free items, positive-only items, and safe early returns, but adds heavier caching around prepared equipment data so repeated runs avoid decoding the same items again.

When negative bonuses are present, Curious still only rechecks the requirements that can actually be affected by those negatives. Before falling back to the pruned DFS, it also tries a greedy pass to catch common cases without opening the full search.

It performs especially well when the same player or equipment prefix is reused, since it can restore precomputed arrays, free-item aggregates, requirement masks, and impact masks instead of rebuilding everything from scratch.

Of course, the best thing to do is to see the algo source code by yourself!

Validation

Tests pass for Curious.
